Hi there!
[tex]\large\boxed{\text{x = 12, x = 5}}[/tex]
Problem 1:
The angles pictured are vertical angles, so each will be equivalent. Therefore:
(5x + 5)° = 65°
Subtract 5 from both sides:
5x = 60
Divide both sides by 5:
x = 12°.
Problem 2:
The two angles are supplementary, so they add up to 180°. Therefore:
180° = (9x)° + (12x + 75)°
180 = 9x + 12x + 75
Combine like terms:
180 = 21x + 75
Subtract 75 from both sides:
105 = 21x
Divide both sides by 21:
x = 5°.

Select the ordered pair that is a solution of the system of linear equations.
y = 4x - 7
y = -x +3
o (1,2)
o (2,1)
o (1,1)
o (2,2)
Answer:
the ordered pair will be (1, 2)
Step-by-step explanation:
first of all substitute the x and y values into the equation in other to make the equation true.
Therefore y=4x-7
1 = 4(2) -7
1 = 8 -7
1 = 1
Making the first equation true. then move to the second equation which is y = - x + 3
1 = -(2) + 3
1 = 1
I hope this helps though

What is the value of x?
4x+2-(3+3x)=7
Answer:
x= 8
Step-by-step explanation:
Step 1- Distribute into the parenthesis by 1.
4x+2+3(-1)+3(-1)x= 7
Step 2- Simplify.
4x+2-3-3x= 7
Step 3- Add common variables.
(4x-3x)+(2-3)
1x-1= 7
Step 4- Add 1 to both sides.
1x-1= 7
+1 +1
1x= 8
Step 5- Divide both sides by 1.
1x= 8
1 1
x= 8
Can you give me a Brainliest
plz plz plz plz plz plz
Answer:x=8
Step-by-step explanation:
4x+2-(3+3x)=7
Distribute -1 in parentheses because there is an invisible 1
4x+2-3-3x=7
Combine like terms
X-1=7
Add one on both sides
x=8
Find LN.
A. 38
B. 56
C. 58
D. 76
Answer:
B. 56°
Step-by-step explanation:
[tex] 20 \degree = \frac{1}{2} (96 \degree - \widehat{LN}) \\ \\ 2 \times 20 \degree = (96 \degree - \widehat{LN}) \\ \\ 40 \degree = (96 \degree - \widehat{LN }) \\ \\ \widehat{ln} = 96 \degree - 40 \degree \\ \\ \huge \red{ \widehat{LN} = 56 \degree}[/tex]

what changes in a wave to make a sound high pitch or low pitch?
Answer:
Volume is dependent on how hard the air is pushed through. Sound travels more slowly than light. Sound waves travel at the same speed, but vibrate in different ways. Some vibrate quickly and have a high frequency or pitch, while others vibrate slowly and give a lower pitch.

Midpoint of (-6, 3) and (8, -7)
Answer:
Midpoint of (-6, 3) and (8, -7) is: (1, -2)
Step-by-step explanation:
Given the points
(-6, 3)(8, -7)Computing the midpoint of (-6, 3) and (8, -7) using the formula
⇒ [tex]\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-6,\:3\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)[/tex]
⇒ [tex]\left(\frac{8-6}{2},\:\frac{-7+3}{2}\right)[/tex]
⇒ [tex]\left(1,\:-2\right)[/tex]
Therefore, Midpoint of (-6, 3) and (8, -7) is: (1, -2)
if a scarf is 25 percent off and normally cost 20 dollars how much will it cost after 6.5 percent sales tax is paid?
Answer:
$15.98
Step-by-step explanation:
25% off means it is 75% of its normal cost
0.75 x 20 = 15
The scarf is $15 after 25% discount. Then we calculate its final cost after tax:
6.5% = 0.065
1.065 x 15 = 15.975 which rounds to $15.98
Answer: 15.98
Step-by-step explanation: 25% off 20 is 15. 6.5% times 15 is .98 so the answer is 15.98

The graph below shows the relationship between the amount of peanuts and the amount of chocolate in different packages of snack mix for each ounce of peanuts? A.1/2 B.2/3 C.3/4 D.3/2 please i need answers !!!!
Answer:
Option (B)
Step-by-step explanation:
Since the linear graph is passing through the origin, there is a proportional relationship between the amount of chocolate (C) and amount of peanuts (P) used in the package of snacks mix,
P ∝ C
P = kC
k = [tex]\frac{P}{C}[/tex]
Here k = proportionality constant
Since, the given line passes through a point (3, 2),
k = [tex]\frac{2}{3}[/tex]
Therefore, ratio of chocolate and peanuts mixed is [tex]\frac{2}{3}[/tex].
Option (B) is the correct option.

Caitlin has a $10 gift certificate to the music store. She has chosen a number of CDs from the $7 bargain bin. If the cost of the CDs is $32 after the gift certificate is credited, which equation could be used to determine how many CDs did Caitlin buy?
Answer:
32+10=7x
Step-by-step explanation:
Let's solve this first. 32$ is the final price, and then add 10$ because of the gift card, leaving you with 42$. Divide the 42 by 7, because each CD is 7 dollars. The result is 6. So put that into an equation.
32+10=42=7x
x=6!
